7... d6f5  8. d1d8  8... e8d8 Vachier-Lagrave from time to time still tries to defeat the Berlin Defense with the endgame that so exasperated Kasparov in his 2000 match against Kramnik. At the super-GM level, Black has certainly defended well, but I have the impression that amateur chess players underestimate the difficulty of playing this endgame with Black. 9. h2h3  9... c8d7 [%c_arrow d8c8;keyPressed;none;from;d8;opacity;0.8;to;c8;persistent;false,b7b6;keyPressed;none;from;b7;opacity;0.8;to;b6;persistent;false,c8b7;keyPressed;none;from;c8;opacity;0.8;to;b7;persistent;false] Taking the king to c8 and then playing b6-Kb7 is one of the most combative plans for Black.
